SELF-CONTAINED SPINDLE.

SPECIFICATION forming part of Letters Patent No. 551,944, dated December24, 1895.

Application filed August 7, 1895. Serial No. 558,522. (No model.)

To all whom it may concern.'

Be it known that I, JAMES BODDEN, a subject of the Queen of GreatBritain and Ireland, residing atOldham, in the county of Lancaster,England, have invented improvements applicable to the lubrication ofwhat are known as self-contained spindles used in ring-and-traveler andother spinning and doubling frames, of which the following is aspecification.

This invention relates to an improved device for lubricating what areknown as selfcontained spindles used in ring-and-traveler and otherspinning and doubling frames, and also flier throstle-spindles of thesame type. In these frames it is customary to clean and oil the spindlesby iirst pumping out the old oil and sediment, and then applying freshoil, during which operation it is necessary to stop the revolution ofthe spindles and to lift them out of their sockets or holsters. Thisinvention is for the purpose of cleaning and oiling this class ofspindle without having either to stop the spindle or to pump the old oilout.

The nature of my said invention and the manner in which the same is tobe -carried into practical effect will be readily understood onreference to the sheet of drawings here. unto annexed, and the followingexplanation thereof.

Figure l on the drawings is a vertical section of a self-containedring-frame spindle with my improved lubricating device shown as appliedthereto, and Fig. 2 is an elevation of the same with the improvedlubricating device shown as detached. Fig. 3 is an enlarged view of adetached portion of the same, hereinafter more particularly referred to.

a is the spindle, l) the bolster, and c the fixed bolster-case.

For the purposes of my invention I bore up the shank of the bolster-casec from beneath,

as shown at Fig. l, in order to insert therein a lubricating tube or cupd containing oil, this tube or cup d having its upper end formedslightly conical or rounded, as seen at d+ on the enlargedview, Fig. 3,and screwed against a shoulder c+ formed in the bore of the bolster-casec for that purpose, such shoulder being preferably left square and sharpso that the upper end of the bolster-case beds against it and so makes atight joint for itself, or the shoulder may be slightly coned to iit theupper end of the tube. For facility of quick application and fixing ofthis tube or oil-cup el in its place and easy and rapid removaltherefrom I provide the same with a multiplethreaded screw (see Fig. 2)of any suitable pitch and number of threads, and I chase the inside ofthe bore of the shank of the bolstercase with a corresponding multiplethread, so that only a portion of a turn of the tube or oilcup CZ isnecessary to detach or attach the same. The lower end of the oil tube orcup at CZ++ is squared or otherwise prepared to receive a key or similarinstrument for fixing or uniiXing the same.

I claim as my invention- The combination with a spindle, of an'internaltube or oil cup inserted in the bolster case and having a taper orconical end to increase frictional contact and to make an oil tightjoint, the exterior of such tube being provided with a multiple threadedscrew and the interior of the bore of the bolster case being also chasedwith a similar multiplethreaded screw, substantially as and for thepurposes set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES BODDEN.-
